I was surprised to read Magnus's post about needing to replace some units with Minotaurs or Hydras – but what would be left for the Warlocks? Besides, why are dragons a must?
Ple-San, read the unit descriptions – there's a levitating Seer and a teleporting Night Sorceress. The idea of climbing through walls is interesting, but it's already been used in the pseudo-Chinese faction.
At the very least, they could have been combined, like they did in Heroes 5.
